Hi Chris and welcome,
Sounds like you are doing just fine. Keep practising the grouping and the scores will come; funny how when you chase scores they don't come... The secret is to accept that every shot will not be a 10.9, that if you do the process correctly, the shot will land inside whatever group you are capable of. Hold the 9 ring and you'll be shooting 560s - so if you work on grouping as you are doing you sail past 540 and need to buy yourself a new gun :-)

Sorry I can't help with clubs or coaches in your area, but I'll PM you a draft document that might be of interest.

Cheers
McT
